Aerodynamics to improve the golf swing and speed of the driver

The present invention relates to a golf club, and more particularly to a driver who uses aerodynamics to improve the sound and speed of a golf swing.

In golf, let the user improve the swing speed of the club when serving, and make the golf ball reach a farther distance. It is a key project for the development of golf driver. In order to achieve the aforementioned goals of increasing the swing speed and achieving a farther pitch, how to develop an aerodynamic shape of the driver's head is an important factor.

At present, the existing golf driver is composed of a long rod body and a head connected to the bottom end of the long rod body, the head includes a hollow head body and a neck connected to a front end side of the head body The part is connected to the long rod by the rod neck. The hollow head body includes a casing and a ball striking panel disposed on a front side of the casing, the casing forming an arcuate streamlined body.

The conventional golf club described above can use the streamlined head body to reduce the air resistance when hitting the ball. However, in terms of aerodynamics, when the user holds the golf driver's swing and hits the ball, the airflow flows backwards with the hitting panel of the driver's club head toward the airflow, and the airflow is respectively The crown of the housing of the head body passes through the bottom plate of the housing, and passes along the curved sidewall surface on both sides of the head. Due to the viscosity between the airflow and the curved sidewall, the air resistance is still too large, and It is difficult for the user to obtain a sound such as a pleasant sound when swinging.

In addition, in the field of golf clubs, in order to reduce the air resistance during the movement of the club head, a plurality of front apertures having a smaller aperture are provided on the front panel of the club head, and at the end of the casing of the club head.
